This series fixes our handling of the PCI INTD interrupts in both Xilinx PCIe controller drivers, and cleans up a wasted IRQ domain entry in the Altera PCIe controller driver. It also adds a common PCI_INTX_NUM definition which all relevant drivers under drivers/pci/host/ are adjusted to make use of. - Patch 1 moves enum pci_interrupt_pin to somewhere we can use it from PCI host code. - Patch 2 introduces a helper function to translate 1-4 INTx ranges into the 0-3 range, by using it as a struct irq_domain's xlate callback. - Patches 3 adjusts the Altera driver to avoid wasting an IRQ domain entry. - Patches 4 & 5 fix the INTD interrupt for Xilinx PCIe drivers. - Patches 6-8 make use of PCI_NUM_INTX to replace custom definitions or magic numbers in drivers. The series versioning is continuing on from that of my "PCI: xilinx: Fixes, optimisation & MIPS support" series which some of the earlier patches were originally a part of, in order to prevent individual patches from jumping backwards in versioning. Applies atop v4.13-rc5.
